Abstract (en)

[origin: US4387476A] In the process of washing synthetic fibers directly subsequent to the spinning process in which the tow is deposited in a folded condition onto a transportation device, the solvent is removed as completely as possible with the use of as little fresh water as possible if the washing process is carried out on the folded tow in counterflow on this transporting device.
